ABSTRACT:
A cap-sensitive slurry explosive capable of propagating a high order detonation in thin layers and which has a high degree of safety for a cap-sensitive explosive. The slurry consists of a superfine grained explosive, suspended in an energetic, but non-self-explosive liquid matrix and contains no liquid explosive ingredient. The slurry resists dispersion in a variety of liquids including water and crude oil. In the preferred embodiments the slurries include penetaerythritol tetranitrate (PETN) in super fine particles, having an average particle size of 6.5 microns.
